FIELD

The present disclosure relates to pharmaceutical compositions and methods suitable for treating gastrointestinal (GI) disorders, such as chronic fatigue syndrome.

BACKGROUND

Mammals harbor diverse microbial species in their gastrointestinal (GI) tracts. Interactions between these microbes and between microbes and the host, e.g. the host immune system, shape a microbiota. A healthy microbiota provides the host with multiple benefits, including colonization resistance to a broad spectrum of pathogens, essential nutrient biosynthesis and absorption, and immune stimulation that maintains a healthy gut epithelium and an appropriately controlled systemic immunity. An unbalanced microbiota (also called ‘dysbiosis’ or disrupted symbiosis) may lose its function and results in increased susceptibility to pathogens, altered metabolic profiles, or induction of proinflammatory signals that can lead to local or systemic inflammation or autoimmunity. Additionally, such a disrupted microbiota may be infected by incoming pathogen or pathogens, which can cause pain, diarrhea, gas, and constipation among other symptoms. Hence, the intestinal microbiota plays a significant role in the pathogenesis of many disorders such as pathogenic infections of the gut.

Implantation or administration of human colonic microbiota into the bowel of a sick patient is called Fecal Microbiota Transplantation (FMT), also commonly known as fecal bacteriotherapy. FMT is believed to repopulate the gut with a diverse array of microbes that control key pathogens by creating an ecological environment inimical to their proliferation and survival. It represents a therapeutic protocol that allows a fast reconstitution of a normal compositional and functional gut microbial community.

FMT has been used to treat Clostridium difficile infection (CDI). FMT has also been suggested in treating other gut infective agents such as E. coli and Vancomycin resistant Enterococci (VRE). It entails infusions through a colonoscope, an enema or via a nasojejunal tube of human microbiota either in the form of homogenised stool, or cultured stool components such as Clostridia, to implant in the colon and thereby displace or eradicate pathogenic bacteria, e.g., C. difficile.

Chronic fatigue syndrome (CFS) is a debilitating and complex disorder characterized by extreme fatigue that is not improved by bed rest. This disorder can worsen with ongoing mental and physical activity. There is no cure for chronic fatigue syndrome and no prescription drugs have been developed specifically for this disease to date. Thus, there is a need for treatments for chronic fatigue syndrome.

DETAILED DESCRIPTION

Unless defined otherwise herein, terms are to be understood according to conventional usage by those of ordinary skill in the relevant art.

As used herein, the term “treating” refers to (i) completely or partially inhibiting a disease, disorder or condition, for example, arresting its development; (ii) completely or partially relieving a disease, disorder or condition, for example, causing regression of the disease, disorder and/or condition; or (iii) completely or partially preventing a disease, disorder or condition from occurring in a patient that may be predisposed to the disease, disorder and/or condition, but has not yet been diagnosed as having it. Similarly, “treatment” refers to both therapeutic treatment and prophylactic or preventative measures.

As used herein, “therapeutically effective amount” or “pharmaceutically active dose” refers to an amount of a composition which is effective in treating the named disease, disorder or condition.

As used herein, “microbiota,” and “flora” refer to a community of microbes that live in or on a subject's body, both sustainably and transiently, including eukaryotes, archaea, bacteria, and viruses (including bacterial viruses (i.e., phage)). A non-selected fecal microbiota refers to a community or mixture of fecal microbes derived from a donor's fecal sample without selection and substantially resembling microbial constituents and population structure found in such fecal sample.

As used herein, a “sterile fecal filtrate” or a “non-cellular fecal filtrate” refers to a liquid component of a fecal material, where the liquid component is free or substantially free of cell-based living organisms (e.g., bacteria, fungi, or their spores), but retains bacteriophages and non-cellular biological materials. Preferably, a non-cellular or sterile fecal filtrate is also free of viruses for eukaryotic host cells.

As used herein, “remission, cure, or resolution rate” refers to the percentage of patients that are cured or obtain remission or complete resolution of a condition in response to a given treatment. Remission, cure, or resolution of ulcerative colitis refers to complete cessation of fatigue and ancillary symptoms. Quantitatively, remission, cure, or resolution is achieved when a patient's Chronic Fatigue Syndrome severity score is below 3 and Sum8 score is below or equal to 14, assessed after 8 weeks of treatment. Remission, cure, or resolution can be further confirmed by functional Magnetic resonance imaging (fMRI) and proteomic analysis.

As used herein, “response rate” refers to the percentage of patients that respond positively (e.g., reduced severity or frequency of one or more symptoms) to a given treatment. Quantitatively, a patient responds to a treatment positively when the patient's Sum8 score decreases by at least 2 from baseline to week 8.

As used herein, “Chronic Fatigue Syndrome Severity Score” or “fatigue severity score” refers to an index system for assessing the symptomatic severity or response of a chronic fatigue syndrome patient. See Baraniuk et al., A Chronic Fatigue Syndrome (CFS) severity score based on case designation criteria. Am. J. Transl. Res. 2013;5(1):53-68. The index is a subjective evaluation of the patient's severity of fatigue experienced in the previous 6 months. A score of 0 would be assigned to no symptoms, 1 for trivial, 2 for mild, 3 for moderate, and 4 for severe. This index is used in conjunction with “Sum8” ancillary scoring, which assesses eight variables, including problems with memory or concentration, sore throat, tender lymph node regions, myalgia, arthralgia, headaches, sleep disturbances, and exertional exhaustion. See Baraniuk et al. Each variable is scored from 0-4 so that the total index score ranges from 0-32. A Sum8≥14 accompanied with a fatigue severity score of 3 or 4 indicates that the subject is experiencing chronic fatigue syndrome. A sum8≤14 accompanied with a fatigue severity score of 3 or 4 indicates that the subject is experiencing chronic idiopathic fatigue. A sum8≥14 accompanied with a fatigue severity score of 0,1, or 2 indicates that the subject is experiencing CFS-like with insufficient fatigue syndrome.

As used herein, “isolated” or “purified” refers to a bacterium or other entity or substance that has been (1) separated from at least some of the components with which it was associated when initially produced (whether in nature or in an experimental setting), and/or (2) produced, prepared, purified, and/or manufactured by the hand of man. Isolated or purified bacteria can be separated from at least about 10%, about 20%, about 30%, about 40%, about 50%, about 60%, about 70%, about 80%, about 90%, or more of the other components with which they were initially associated.

As used herein, “cytotoxic” activity or bacterium includes the ability to kill a bacterial cell, such as a pathogenic bacterial cell. A “cytostatic” activity or bacterium includes the ability to inhibit, partially or fully, growth, metabolism, and/or proliferation of a bacterial cell, such as a pathogenic bacterial cell.

As used herein, the terms “pathogen” and “pathogenic” in reference to a bacterium or any other organism or entity includes any such organism or entity that is capable of causing or affecting a disease, disorder or condition of a host organism containing the organism or entity.

As used herein, “spore” or a population of “spores” includes bacteria (or other single-celled organisms) that are generally viable, more resistant to environmental influences such as heat and bacteriocidal agents than vegetative forms of the same bacteria, and typically capable of germination and out-growth. “Spore-formers” or bacteria “capable of forming spores” are those bacteria containing the genes and other necessary abilities to produce spores under suitable environmental conditions.

As used herein, a “combination” of two or more bacteria includes the physical co-existence of the two bacteria, either in the same material or product or in physically connected products, as well as the temporal co-administration or co-localization of the two bacteria.

As used herein, “Shannon Diversity Index” refers to a diversity index that accounts for abundance and evenness of species present in a given community using the formula

$H = {- {\sum\limits_{i = 1}^{R}{p_{i}\ln \; p_{i}}}}$

where H is Shannon Diversity Index, R is the total number of species in the community, and p_(i) is the proportion of R made up of the ith species. Higher values indicate diverse and equally distributed communities, and a value of 0 indicates only one species is present in a given community.

As used herein, an “intermittent dosing schedule” means that that a therapeutic composition is administered for a period of time followed by a period of time (a treatment period) where treatment with such therapeutic composition is withheld (a rest period). Intermittent dosing regimens can be expressed as treatment period in days or weeks/rest period in days or weeks. For example, a 4/1 intermittent dosing schedule refers to an intermittent dosing schedule where the treatment period is four weeks/days and the rest period is one week/day.

As used herein, a “continuous dosing schedule” refers to a dosing schedule where a therapeutic composition is administered during a treatment period without a rest period. Throughout the treatment period of a continuous dosing schedule, a therapeutic composition can be administered, for example, daily, or every other day, or every third day, or weekly. On a day when a therapeutic composition is administered, it can be administered in a single dose, or in multiple doses throughout the day.

As used herein, “dosing frequency” refers to the frequency of administering doses of a therapeutic composition in a given time. Dosing frequency can be indicated as the number of doses per a given time, for example, once per day, once a week, or once in two weeks.

As used herein, “dosing interval” refers to the amount of time that elapses between multiple doses being administered to a subject.

Chronic fatigue syndrome is a disease that is characterized by severe fatigue for six or more consecutive months that is not due to ongoing exertion or other medical conditions associated with fatigue. Such fatigue is not improved by bedrest and significantly interferes with daily activities and work. Chronic fatigue syndrome differs from the other fatigue conditions in that an individual diagnosed with the syndrome concurrently has 4 or more of the following symptoms: post-exertion malaise lasting more than 24 hours; unrefreshing sleep; significant impairment of short-term memory or concentration; muscle pain; multi-joint pain without swelling or redness; headaches of a new type, pattern, or severity; tender cervical or axillary lymph nodes; a sore throat that is frequent or recurring.

The cause of chronic fatigue syndrome is unknown. Healthcare practitioners identified that virus infection, hypotention, weakened immune system, and hormonal imbalances as possible contributing factors that causes the syndrome. The Centers for Disease Control and Prevention (CDC) suggests that chronic fatigue syndrome is the end stage of multiple different conditions, including Epstein-Barr virus infection and Ross River virus infection. Because many conditions have symptoms similar to chronic fatigue syndrome, such as mononucleosis, Lyme disease, multiple sclerosis, lupus, hypothyroidism, fibromyalgia, and major depressive disorder. Hence, a physician must rule out these clinical conditions before diagnosing that a patient has chronic fatigue syndrome.

Chronic fatigue syndrome occurs most often in people ages 40 to 60, although the disease may afflict people of any age. It affects women four times more frequently than men and appears to run in some families.

Other fatigue conditions exist. As used herein, “chronic idiopathic fatigue” or “CIF” refers to a condition where a subject experiences six or more consecutive months of severe fatigue, but experiences less than 4 of the symptoms listed in [0045]. As used herein, “CFS-like with insufficient fatigue syndrome” or “CFSLWIFS” refers to a condition where a subject experiences low fatigue while experiencing 4 or more of the symptoms listed in [0045].

Several theories have been proposed for the cause of chronic fatigue syndrome, yet no single cause have been identified. There is some evidence to suggest that certain infections may cause or trigger chronic fatigue syndrome. However, no single infection or pathogen has been identified to cause chronic fatigue syndrome. Some studies suggest that changes in an individual's immune system upon infection may lead to chronic production of cytokines, resulting in chronic fatigue syndrome. Altered hormonal balance (e.g. corticotrophin-releasing hormone and cortisol) may also influence the immune system to cause chronic fatigue syndrome. There is also a study relating chronic fatigue syndrome with abdominal symptoms. See Berstad et al., Functional bowel symptoms, fibromyalgia and fatigue: A food-induced triad? Scand J. Gastroenterol. 2012; 47(8-9):914-19.

Chronic fatigue syndrome may cause long-term problems in an individual including feelings of anger, guilt, anxiety, isolation, and abandonment. Other quality of life issues may arise including a decrease of stamina that interferes with activities of daily life, memory and concentration problems that seriously hurt work or school performance, loss of independence, livelihood, and economic security, and alterations in relationships with family and friends. These problems can disappear when the chronic fatigue syndrome is treated effectively.

There is no cure for chronic fatigue syndrome. Treatment programs are generally individualized to the needs and symptoms experienced by the patient. No drug is available for treating chronic fatigue syndrome itself, and physicians are discouraged to use medications to treat the symptoms because of the patients' sensitivity to drugs in general. Some non-drug therapies may include acupuncture, gentle massage, deep breathing, relaxation therapy, or yoga to increase energy and decrease pain. Other coping strategies may include professional counselling, attending a support group, and changing employment condition to one that is favorable to support chronic fatigue syndrome individuals.

Many chronic diseases and disorders of the GI tract have chronic infection/infestation as their underlying pathological conditions (e.g., chronic fatigue syndrome). In one aspect, the present disclosure includes and relates to the use of a fecal microbiota, one or more microbial species therefrom, an active fragment or component therefrom for the treatment and/or prophylaxis of various disease states (e.g., chronic fatigue syndrome) related to the presence of ‘abnormal’ microflora in the GI tract. An active fragment of a bacterium can be any active molecule isolated from such bacteria by any known method for preparing/identifying active fragments of bacteria and proteins secreted from bacteria. Such methods include but are not limited to the following: sonication, osmotic shock, detergent lysis, high pressure, transfer appropriate DNA to other organisms, such as bacteria, plant or animal that is then used as a feed additive as described previously. In one aspect, an active fragment or component of a bacterium is selected from the group consisting of a mycolate or a derivative thereof, a polysaccharide, a lipoglycan, a small peptide, a thiopeptide, a protein, a nucleic acid molecule, a metabolite, a cell wall component, or any combination thereof.

In another aspect, a sterile fecal filtrate comprises a non-cellular non-particulate fecal component. In one aspect, a sterile fecal filtrate is made as described in WO2014/078911, published May 30, 2014. In another aspect, a sterile fecal filtrate is made as described in Ott et al., Gastroenterology 152:799-911(2017).

In one aspect, a fecal filtrate comprises secreted, execreted or otherwise liquid components or a microbiota, e.g., biologically active molecules (BAMs), which can be antibiotics or anti-inflammatories, are preserved, retained or reconstituted in a flora extract.

In one aspect, an exemplary therapeutic composition comprises starting material from a donor from a defined donor pool, where this donor contributes a stool that is centrifuged, then filtered with very high-level filtration using e.g., either metal sieving or Millipore filters, or equivalent, to ultimately permit only cells of bacterial origin to remain, e.g., often less than about 5 micrometers diameter. After the initial centrifugation, the solid material is separated from the liquid, and the solid is then filtered in progressively reducing size filters and tangential filters, e.g., using a Millipore filtration, and optionally, also comprising use of nano-membrane filtering. The filtering can also be done by sieves as described in WO 2012/122478, but in contrast using sieves that are smaller than 0.0120 mm, down to about 0.0110 mm, which ultimately result in having only bacterial cells present.

The supernatant separated during centrifugation is now taken and filtered progressively in a filtering, e.g., a Millipore filtering or equivalent systems, to end up with liquid which is finely filtered through an about 0.22 micron filter. This removes all particulate matter including all living matter, including bacteria and viruses. The product then is sterile, but the aim is to remove the bacteria but to keep their secretions, especially antimicrobial bacteriocins, bacteria-derived cytokine-like products and all accompanying Biologically Active Molecules (BAMs), including: thuricin (which is secreted by bacilli in donor stools), bacteriocins (including colicin, troudulixine or putaindicine, or microcin or subtilosin A), lanbiotics (including nisin, subtilin, epidermin, mutacin, mersacidin, actagardine, cinnamycin), lacticins and other antimicrobial or anti-inflammatory compounds.

In one aspect, a therapeutic composition used here comprises a reconstituted fecal flora consisting essentially of a combination of a purified fecal microbiota and a non-cellular fecal filtrate. In another aspect, a therapeutic composition used here comprises a purified fecal microbiota supplemented with one or more non-cellular non-particulate fecal components. In one aspect, a therapeutic composition used here comprises one or more non-cellular non-particulate fecal components. In one aspect, one or more non-cellular non-particulate fecal components comprise synthetic molecules, biologically active molecules produced by a fecal microorganism, or both. In another aspect, one or more non-cellular non-particulate fecal components comprise biologically active proteins or peptides, micronutrients, fats, sugars, small carbohydrates, trace elements, mineral salts, ash, mucous, amino acids, nutrients, vitamins, minerals, or any combination thereof. In one aspect, one or more non-cellular non-particulate fecal components comprise one or more biologically active molecules selected from the group consisting of bacteriocin, lanbiotic, and lacticin. In another aspect, one or more non-cellular non-particulate fecal components comprise one or more bacteriocins selected from the group consisting of colicin, troudulixine, putaindicine, microcin, and subtilosin A. In one aspect, one or more non-cellular non-particulate fecal components comprise one or more lanbiotics selected from the group consisting of thuricin, nisin, subtilin, epidermin, mutacin, mersacidin, actagardine, and cinnamycin. In another aspect, one or more non-cellular non-particulate fecal components comprise an anti-spore compound, an antimicrobial compound, an anti-inflammatory compound, or any combination thereof. In a further aspect, one or more non-cellular non-particulate fecal components comprise an interleukin, a cytokine, a leukotriene, an eicosanoid, or any combination thereof.

In another aspect, a treatment method provided here comprises the use of both fecal bacterial cells, e.g., a partial or a complete representation of the human GI microbiota, and an isolated, processed, filtered, concentrated, reconstituted and/or artificial liquid component (e.g., fecal filtrate) of the flora (the microbiota) which comprises, among others ingredients, bacterial secretory products such as e.g., bacteriocins (proteinaceous toxins produced by bacteria, including colicin, troudulixine or putaindicine, or microcin or subtilosin A), lanbiotics (a class of peptide antibiotics that contain a characteristic polycyclic thioether amino acid lanthionine or methyllanthionine, and unsaturated amino acids dehydroalanine and 2-aminoisobutyric acid; which include thuricin (which is secreted by bacilli in donor stools), nisin, subtilin, epidermin, mutacin, mersacidin, actagardine, cinnamycin), a lacticin (a family of pore-forming peptidic toxins) and other antimicrobial or anti-inflammatory compounds and/or additional biologically active molecules (BAMs) produced by bacteria or other microorganisms of the microbiota, and/or which are found in the “liquid component” of a microbiota.

In one aspect, a fecal bacteria-based therapeutic composition is used concurrently with a fecal non-cellular filtrate-based therapeutic composition. In another aspect, a patient is treated with a first fecal non-cellular filtrate-based therapeutic composition before being given a second fecal bacteria-based therapeutic composition, or vice versa. In a further aspect, a treatment method comprises three steps: first, antibiotic pre-treatment to non-selectively remove infectious pathogen(s); second, a fecal non-cellular filtrate-based treatment step to further suppress selected infectious pathogen(s); and third, giving the patient a fecal bacteria-based therapeutic composition to re-establish a functional intestinal microbiome.

In an aspect, a therapeutic composition is combined with other adjuvants such as antacids to dampen bacterial inactivation in the stomach. (e.g., Mylanta, Mucaine, Gastrogel). In another aspect, acid secretion in the stomach could also be pharmacologically suppressed using H2-antagonists or proton pump inhibitors. An example H2-antagonist is ranitidine. An example proton pump inhibitor is omeprazole. In one aspect, an acid suppressant is administered prior to administering, or in co-administration with, a therapeutic composition.

In an aspect, a therapeutic composition is in the form of: an enema composition which can be reconstituted with an appropriate diluent; enteric-coated capsules; enteric-coated microcapsules; acid-resistant tablet; acid-resistant capsules; acid-resistant microcapsules; powder for reconstitution with an appropriate diluent for naso-enteric infusion or colonoscopic infusion; powder for reconstitution with appropriate diluent, flavoring and gastric acid suppression agent for oral ingestion; powder for reconstitution with food or drink; or food or food supplement comprising enteric-coated and/or acid-resistant microcapsules of the composition, powder, jelly, or liquid.

In an aspect, a treatment method effects a cure, reduction of the symptoms, or a percentage reduction of symptoms of chronic fatigue syndrome. The change of flora is preferably as “near-complete” as possible and the flora is replaced by viable organisms which will crowd out any remaining, original flora. Typically the change in enteric flora comprises introduction of an array of predetermined flora into the gastro-intestinal system, and thus in a preferred form the method of treatment comprises substantially or completely displacing pathogenic enteric flora in patients requiring such treatment.

In another aspect, a therapeutic composition can be provided together with a pharmaceutically acceptable carrier. As used herein, a “pharmaceutically acceptable carrier” refers to a non-toxic solvent, dispersant, excipient, adjuvant, or other material which is mixed with a live bacterium in order to permit the formation of a pharmaceutical composition, e.g., a dosage form capable of administration to the patient. A pharmaceutically acceptable carrier can be liquid (e.g., saline), gel or solid form of diluents, adjuvant, excipients or an acid resistant encapsulated ingredient. Suitable diluents and excipients include pharmaceutical grades of physiological saline, dextrose, glycerol, mannitol, lactose, starch, magnesium stearate, sodium saccharin, cellulose, magnesium carbonate, and the like, and combinations thereof. In another aspect, a therapeutic composition may contain auxiliary substances such as wetting or emulsifying agents, stabilizing or pH buffering agents. In an aspect, a therapeutic composition contains about 1%-5%, 5%-10%, 10%-15%, 15-20%, 20%-25%, 25-30%, 30-35%, 40-45%, 50%-55%, 1%-95%, 2%-95%, 5%-95%, 10%-95%, 15%-95%, 20%-95%, 25%-95%, 30%-95%, 35%-95%, 40%-95%, 45%-95%, 50%-95%, 55%-95%, 60%-95%, 65%-95%, 70%-95%, 45%-95%, 80%-95%, or 85%-95% of active ingredient. In an aspect, a therapeutic composition contains about 2%-70%, 5%-60%, 10%-50%, 15%-40%, 20%-30%, 25%-60%, 30%-60%, or 35%-60% of active ingredient.

In an aspect, a therapeutic composition can be incorporated into tablets, drenches, boluses, capsules or premixes. Formulation of these active ingredients into such dosage forms can be accomplished by means of methods well known in the pharmaceutical formulation arts. See, e.g., U.S. Pat. No. 4,394,377. Filling gelatin capsules with any desired form of the active ingredients readily produces capsules. If desired, these materials can be diluted with an inert powdered diluent, such as sugar, starch, powdered milk, purified crystalline cellulose, or the like to increase the volume for convenience of filling capsules.

In an aspect, conventional formulation processes can be used to prepare tablets containing a therapeutic composition. In addition to the active ingredients, tablets may contain a base, a disintegrator, an absorbent, a binder, and a lubricant. Typical bases include lactose, sugar, sodium chloride, starch and mannitol. Starch is also a good disintegrator as is alginic acid. Surface-active agents such as sodium lauryl sulfate and dioctyl sodium sulphosuccinate are also sometimes used. Commonly used absorbents include starch and lactose. Magnesium carbonate is also useful for oily substances. As a binder there can be used, for example, gelatin, gums, starch, dextrin, polyvinyl pyrrolidone and various cellulose derivatives. Among the commonly used lubricants are magnesium stearate, talc, paraffin wax, various metallic soaps, and polyethylene glycol.

In an aspect, for preparing solid compositions such as tablets, an active ingredient is mixed with a pharmaceutical carrier, e.g., conventional tableting ingredients such as corn starch, lactose, sucrose, sorbitol, talc, stearic acid, magnesium stearate, dicalcium phosphate or gums, or other pharmaceutical diluents, e.g. water, to form a solid preformulation composition containing a homogeneous mixture of a composition of the present invention. When referring to these preformulation compositions as homogeneous, it is meant that the active ingredient is dispersed evenly throughout the composition so that the composition may be readily subdivided into equally effective unit dosage forms such as tablets, pills and capsules. This solid preformulation composition is then subdivided into unit dosage forms of the type described above containing a desired amount of an active ingredient (e.g., at least about 10⁵, 10⁶, 10⁷, 10⁸, 10⁹, 10¹⁰, 10¹¹, 10¹², or 10¹³ cfu). A therapeutic composition used herein can be flavored.

In an aspect, a therapeutic composition can be a tablet or a pill. In one aspect, a tablet or a pill can be coated or otherwise compounded to provide a dosage form affording the advantage of prolonged action. For example, a tablet or pill can comprise an inner dosage and an outer dosage component, the latter being in the form of an envelope over the former. The two components can be separated by an enteric layer which serves to resist disintegration in the stomach and permits the inner component to pass intact into the duodenum or to be delayed in release. A variety of materials can be used for such enteric layers or coatings, such materials including a number of polymeric acids and mixtures of polymeric acids with such materials as shellac, cetyl alcohol and cellulose acetate.

In an aspect, a therapeutic composition can be a drench. In one aspect, a drench is prepared by choosing a saline-suspended form of a therapeutic composition. A water-soluble form of one ingredient can be used in conjunction with a water-insoluble form of the other by preparing a suspension of one with an aqueous solution of the other. Water-insoluble forms of either active ingredient may be prepared as a suspension or in some physiologically acceptable solvent such as polyethylene glycol. Suspensions of water-insoluble forms of either active ingredient can be prepared in oils such as peanut, corn, sesame oil or the like; in a glycol such as propylene glycol or a polyethylene glycol; or in water depending on the solubility of a particular active ingredient. Suitable physiologically acceptable adjuvants may be necessary in order to keep the active ingredients suspended. Adjuvants can include and be chosen from among the thickeners, such as carboxymethylcellulose, polyvinyl pyrrolidone, gelatin and the alginates. Surfactants generally will serve to suspend the active ingredients, particularly the fat-soluble propionate-enhancing compounds. Most useful for making suspensions in liquid nonsolvents are alkylphenol polyethylene oxide adducts, naphthalenesulfonates, alkylbenzene-sulfonates, and the polyoxyethylene sorbitan esters. In addition many substances, which affect the hydrophilicity, density and surface tension of the liquid, can assist in making suspensions in individual cases. For example, silicone anti-foams, glycols, sorbitol, and sugars can be useful suspending agents.

In another aspect, a therapeutic composition comprises at most about 10⁵, 10⁶, 10⁷, 10⁸, 10⁹, 10¹⁰, 10¹¹, 10¹², 10¹³ or 10¹⁴ cells or total cell count.

In one aspect, a therapeutic composition is formulated as an oral capsule, microcapsule, tablet, or pill. In another aspect, a capsule, microcapsule, tablet, or pill is adapted for enteric delivery. In a further aspect, a capsule, microcapsule, tablet, or pill is an enteric capsule, microcapsule, tablet, or pill. In another aspect, a capsule, microcapsule, tablet, or pill comprises an enteric coating, is acid resistant, or both.

EXAMPLES Example 1 Preparation of Fecal Microbiota

Fecal microbiota is prepared essentially according to protocols published in US2014/0147417 or WO2014/152484. Summarized below is an exemplary protocol.

Potential fecal microbiota donors are screened according to a list of criteria used to exclude unsuitable donors. Potential fecal microbiota donors are excluded if they have received antibiotics, laxatives, diet pills, immunomodulators or chemotherapy in the preceding three months. Potential fecal microbiota donors are excluded if they have a history of all known infectious diseases, morbid obesity, diabetes, irritable bowel syndrome, inflammatory bowel disease, chronic diarrhea, constipation, colorectal polyps or cancer, a compromised immune system, metabolic syndromes, chronic fatigue syndrome, major GI surgery, or other diseases or conditions potentially associated with specific changes in fecal microbiota. Potential fecal microbiota donors are excluded if they exhibit positive laboratory tests for C-reactive protein, erythrocyte sedimentation rate, hepatitis A, hepatitis B, hepatitis C, human immunodeficiency virus, human T-lymphotropic virus or syphilis. Potential fecal microbiota donors are excluded if they exhibit a positive test for stool ova, parasites or viruses. Potential fecal microbiota donors are excluded if they engage in high-risk sexual behaviors, have been incarcerated, or received any tattoos or body piercings in areas that have had disease epidemics within the past three months.

Donor fecal material (fresh feces) is collected in a sterilized container, and then it is transferred to a blender. Approximately 500-1000 mL 0.9% saline solution is added to the blender and thoroughly mixed with the fecal sample. The resulting suspension is filtered at least 4 times through strainers prior to collecting a final suspension. The final suspension is centrifuged in 50 mL tubes at 1200×g for 3 minutes. The supernatant is discarded and the pellet is gently resuspended in approximately 50 mL of sterile 0.9% saline solution. The centrifugation and resuspension steps are repeated 2 to 4 additional times. Upon the final centrifugation, the supernatant is discarded. If the fecal microbiota is to be used immediately, the resultant pellet is resuspended in 1.5-volumes of 0.9% saline solution by gently mixing. If the fecal microbiota is to be stored, the resultant pellet is resuspended in 10% sterile glycerol and stored at −80 degrees Centigrade. If fecal microbiota are frozen, they are warmed to room temperature prior to administration to a patient

Example 2 Treatment of Chronic Fatigue Syndrome

A total of 60 patients presented with chronic fatigue syndrome (52 CFS patients with irritable bowel syndrome; 4 CFS patients with constipation; and 4 CFS-only patients) are recruited in a study. Five out of 60 patients receive a single transcolonoscopic (TC) infusion of 300 cc culture comprising 13 non-pathogenic enteric bacteria (Bacteriodetes, Clostridia, and E. coli). Fifty-two out of 60 patients undergo a two-day infusion (TC and rectal infusion), while 3 out of 60 patients undergo a three-day rectal infusion schedule (TC and two-day rectal infusion). Response/non-response to the infusion treatment is defined as a resolution or return of CFS symptoms including sleep deprivation and lethargy/fatigue at 4 week after the treatment.

Thirty-five out of 60 patients who undergo initial bacteriotherapy respond to treatment. See FIG. 1. Ten out of 15 patients who fail to respond to the initial bacteriotherapy are offered a second TC infusion and either a follow-up rectal infusion (n=4) or an oral course of cultured bacteria (n=6). Referring to FIG. 1, 7 out of 10 respond to the follow-up dose. Accordingly, 42 out of 60 patients achieve clinical response to bacteriotherapy.

Referring to FIG. 2, of those patients who respond to bacteriotherapy, 37 out of 42 patients also experience resolution of their gastrointestinal symptoms. Of the 18 non-responders, 10 attain improvement of associated gastrointestinal symptoms despite persisting CFS symptoms.

Referring to FIG. 3, at 15-20 year follow-up, 12 out of 60 patients are contactable and 7 out of 12 patients (58%) remain CFS-free. Five out of 12 patients experience CFS recurrence 1.5-3 years post the bacteriotherapy.

Referring to FIG. 4, bacteriotherapy is effective in those patients who have gastrointestinal conditions associated with CFS, and the treatment works to restore normal bacterial colonic concentrations. Namely, a bacterial pathophysiology is emphasized by the resolution of gastrointestinal symptoms in 78% of patients.

Therefore, bacteriotherapy achieves initial success rate of 70% in CFS and 58% sustained response. This result is favorable when compared with other therapies where fewer than 10% recover fully and a further 10%-20% worsen during follow-up. See Afrai and Buchwald. Am J. Psychiatry 2003; 160:221-36.

Example 3 Oral Capsule Treatment Protocol for Chronic Fatigue Syndrome

Patients are divided into four groups (Groups 1 to 4). Group 1 patients are administered a pre-treatment of antibiotics (e.g., Vancomycin and Metronidazole) until diarrhea is controlled. Group 2 receives no antibiotics. Both Groups 1 and 2 receive a pre-colonoscopy bowel prep followed by capsule fecal microbiome therapy. Groups 3 and 4 receive no bowel prep while Group 3, not group 4, also receive an antibiotic pretreatment. Capsules are administered for 18 weeks as follows: two capsules twice-a-day for 14 days, two capsules twice-a-day every other day for 14 days, 4 capsules twice-a-week for 14 days, and 4 capsules once-a-week (e.g., each Monday) for 12 weeks. High dose capsules (total cell count of about 10¹²) are used in loading doses (also called treatment doses) for the initial 4 weeks. Lower dose capsules (total cell count of about 10⁹) are used in maintenance doses for the subsequent 14 weeks. In patients receiving antibiotic pretreatment, capsules are administered one day after ceasing antibiotics. Patient symptoms are observed and clinical examination is performed before, during and post oral capsule treatment. Pre, during and post-treatment DNA metagenomics (2-4 days; 1 week; 6 weeks; 12 weeks) are also carried out. The capsule treatments reverse patient symptoms and result in a clinically normal urge and defecation.

Example 4 Treatment of a Patient with CFS

A 30-year old patient with CFS is treated with fecal microbiome therapy. A treatment regimen including acid resistant/delayed release double encapsulated oral capsules containing lyophilized donor-derived non-selected fecal microbiota is used. The patient's symptoms include moderate bloating, moderate abdominal discomfort, severe fatigue, severe abdominal pain, the feeling of pins and needles in legs, ringing in ears, and depression. The patient experiences 0-1 bowel movements per day. The patient is placed on a 6 week treatment protocol with 10 fresh fecal microbiome therapy liquid rectal enema infusions during the induction period of 2 weeks and 4 capsules (each containing a total cell count of about 10⁹-10¹²) per day for 4 weeks during the maintenance period. At week four post initial treatment, the patient experiences mild bloating, moderate abdominal discomfort, slight improvement in fatigue and cognitive issues, improvement in energy levels and vision. The patient also experiences a slight decrease in sharp abdominal pain and reports improvement in sleeping. At week 5 post initial treatment, the patient no longer experiences bloating and abdominal discomfort has improved to mild. Patient experiences improvement in energy levels, finds it easier to engage whilst participating in activities (e.g., watching TV, reading, and conversing with others). The patient's vision is blurry and cognitive issues are still present but vision and cognitive issues improve compared to before initial treatment. Patient has a 10-20% overall improvement at week 6 post initial treatment. Patient is flushed with Glyco and placed on a higher dose of capsules start at week 7. The patient is weaned off of fecal microbiome therapy as follows: week 7 includes 9 capsules/day; week 8—include 8 capsules/day; weeks 9 include 6 capsules/day; weeks 10-13 include maintenance dose of 4 capsules/day. At the end of week 13, patient has an approximate 40% improvement, has the ability to compose music, travel on band gigs, concentrate on verbal conversations, play light sports such as Frisbee, able to wake up clear-headed, able to observe quality sleep, able to limitedly socialize, brain fog still remains throughout the day, blurry visions comes and goes, still wakes up middle of the night to urinate 4 times/week, and overall has a sense of life returning to normal.

Example 5 Treatment of a Patient with CFS

A 27-year old patient with CFS and C. perfingens is treated with fecal microbiome therapy. A treatment regimen including acid resistant/delayed release double encapsulated oral capsules containing lyophilized donor-derived non-selected fecal microbiota is used. The patient's symptoms include severe bloating, severe abdominal discomfort, severe urgency, severe fatigue, brain fog, flatulence, muscle aches, cramping, and inability to focus. The patient is placed on a 5 week treatment protocol with 5 fecal microbiome therapy liquid rectal enema infusions infusions during the induction period of 1 week and 2 capsules per day for 4 weeks during the maintenance period. As patient sees 10-20% improvement at the end of week 6 post-initial treatment, patient's capsule treatment is extended by 4 weeks. Patient's initial symptoms of fatigue decreases, able to attend work on a full time basis without having to leave work mid-day, brain fog has cleared, muscle aches have decreased and able to exercise more. Patient claims an overall 50-60% improvement from initial-treatment, however patient is still positive for C. perfingens.
